How to Fix Low Water Pressure?

Wondering How to Fix Low Water Pressure?

A New Water Pump Can Help!

Low water pressure can result from several issues, such as too small water mains or equipment failure.

The standard level of mains water pressure is 10 metres/head. What this means is that there is enough pressure to push water to a height of 10m.

With low water pressure at the outlets daily activities and duties in a home, business, school, or complex can quickly become frustrating. If that’s the case in your building, it’s time to figure out the issue.

Are you wondering how to fix low water pressure in your home or business? It may be something as simple as a new pump.

Keep reading for a guide that explains bad water pressure and why you might need a new pump!

How Does a Water Pump Work?

There are essentially two types of water pumps – electric-powered pumps and Engine Driven Pumps.

Engine Driven Pump (Diesel) – these pumps are suited in outdoor situations, like irrigation and rural locations.

Electric-powered pumps – powered directly from an electric supply are perfect for homes and businesses due to the water only having to move a short distance & they are easily connected to power outlets. The most commonly used water pumps for homes are sump pumps, jet pumps, and well pumps.

Jet Pumps

Jet pumps have an electric motor that drives the centrifugal impeller or pump. The impeller works similarly to a merry-go-round as it spins quickly and creates a powerful centrifugal force. That force compresses the water against the exterior of the blade.

The faster the impeller moves, the more water it can expel. It only moves in a single direction, though, so water can only go one way.

When the water leaves the jet, a vacuum is generated, which draws the water in even more. Behind the jet, there’s a venturi tube that increases in diameter and is used for slowing down the water and increasing pressure.

Well Pumps

Also known as a submersible water pump, well pumps function almost the same way as jet pumps, but they’re submerged in the well from which they draw water.

While the jet pump boosts water, the well pump pushes the water out.

Most pumps in this application are submerged in the liquid. The pump motor receives direct current from the power source above ground. When the current is switched on, it starts running and then creates a magnetic field. It’s the magnetic field which causes the rotor to start spinning, and then the pumping system begins to start working.

Sump Pumps

Sump pumps are used to pump water out from the basement. Typically, a sump pump consists of a small pump that gets planted at the lowest level of a building’s basement.

It includes a motor and impeller just like the jet pump, and it functions the same way.

Connected to a socket in the basement, the sump pump is also powered electrically. It’s automated, though, which means as soon as the water reaches a specific level, the sump pump starts pumping and will stop again when the water again reaches the minimal level.

What Causes Low or High Water Pressure?

There are many potential causes of low and high water pressure in a building. Some of the causes of low water pressure are:


Too much demand for water

A broken pressure regulator

Faulty fixtures

Closed valves

Clogged or damaged pipes

Corroded plumbing

The most common cause of water pressure that’s too high is the municipal water supplier. It could be that you live near a hydrant or in a place with lots of hills where the supplier has to use higher pressure to reach all homes in the area. It’s important to stay proactive either way, as both issues can lead to more serious issues or damage.

How Can You Fix Low Water Pressure?

Are you wondering how to fix low hot water pressure in your home? If it’s only the hot water pressure that’s low, it could be that you need your water supply lines cleaned. Or, you might need new pipes. 

Scale and sediment build-up inside water heaters, so it may be that you need to flush it clean. 

To fix low water pressure, you must first identify the root issue. Low water pressure is likely to be a result of the above causes, you should always call a professional to come and make an assessment.

Why Water Pumps Fail or Burn Out?

Water pumps don’t last forever. Sometimes they fail because of their age. If your pump is installed correctly and of high-quality, it should last somewhere between 10 and 15 years.

Poor water quality with bacteria and minerals can significantly lessen the life of a pump, too. You should always get your well liner checked, as that prevents corrosion.

If the well is dry, your pump could burn out. If you have a well tank that’s too small for your home’s needs, it can also cause a pump to run and work too hard. Pumps are mechanical items requiring periodical maintenance and can suffer on occasions from electrical related issues.

It’s vital to choose the best pump and system for your building or complex to ensure it continues working efficiently and for as long as possible.
